CAL SOP Calibration
(Option 001 SOP, must have been configured in Paraly SW 112
PC software)
In the Paraly SW 112 PC software, you specify which buffers are to be used in which
sequence. You can combine buffer solutions from different buffer sets. Please note
that the minimum distance allowed between two buffer solutions is Δ 2 pH.
SOP calibration allows you to:
• use up to 3 buffers for adjustment
• use a 4th point for verification (“verification buffer”)
specify a maximum deviation from the verification buffer
• use buffers from different buffer sets, including a “user buffer”.
Note: To abort calibration, you can press meas at any time.
